The  species  is  well  marked  on  account  of  the  strongly  discolorous 
leaves,  which  are  densely  tawny  pubescent  on  the  under  surface,  and  by 
the  decurrence  of  the  petioles  on  the  stem  thus  causing  the  younger 
branches  to  be  subancipitally  angled,  or  strongly  keeled,  hence  the 
specific  name.

hb.  N.  Y.  Bot.  Garden). 

A  species  somewhat  similar  to  Senecio  trichotomus  Greenm.,  but 
differs  in  having  broader  leaves  and  leafy  open  few-headed  cymes.

Bot.  Garden). 


Nov.,  1912.  CUBAN  SENECIONEJE —  GREENMAN  325 

The  general  aspect  of  this  species  is  similar  to  Senecio  Brittonii 
Greenm.,  but  it  differs  in  having  an  essentially  sessile  inflorescence, 
fewer  heads,  shorter  and  densely  white-pubescent  involucral  bracts,  and 
in  the  characters  of  the  corolla. 

Senecio  pachylepis  Greenman,  sp.  nov. 

Frutex  1.5-2  m.  altus;  caule  lignescente;  ramis  ramulisque  teretibus 
glabris  vel  juventate  dense  cano-tomentosis;  foliis  alternis  petiolatis 
oblongo-obovatis  vel  oblanceolatis  3.5-10  cm.  longis  1.5-3.5  cm-  latis 
utrinque  glabris  ad  apicem  obtusis  sinuato-dentatis  ad  basin  integris 
marginibus  plus  minusve  revolutis;  petiolis  usque  ad  1.5  cm.  longis; 
inflorescentiis  terminalibus  cymosis  sessilibus;  capitulis  discoideis  caly- 
culatis;  involucri  squamis  8  lanceolatis  vel  lanceolato-oblongis  4-5  mm. 
longis  obtusis  vel  acutis  glabris  vel  parce  arachnoideo-tomentosis, 
bracteolis  calyculatis  5  spathulatis  2-3.5  mm-  longis  i  mm.  latis  obtusis 
crassiusculis ;  floribus  10-12  flavibus;  pappi  setis  fulvis;  achaeniis 
striatis  hirtellis. —  Along  rocky  river  trail,  Rio  Yamaniguey  to  Camp 
Tao,  Oriente,  Cuba,  22-26  February,  1910,  /.  A.  Shafer,  no.  4008 
(hb.  Field  Museum,  cat.  no.  294785,  type,  and  hb.  N.  Y.  Bot.  Garden). 

In  habit  and  foliar  characters  this  species  resembles  S.  eriocarphus 
Greenm.,  but  differs  in  having  a  close  matted  tomentum  on  the  young 
branches,  glabrous  leaves,  smooth  or  slightly  arachnoid  involucral 
bracts,  and  finally  in  having  strongly  spatulate  and  thickened  calyc- 
ulate  bracteoles.  The  plant  cited  under  the  above  number  has  been 
referred  to  S.  plumbeus  Griseb.;  but  from  that  species,  which  it  resembles 
in  habit  and  in  foliar  characters,  it  is  readily  distinguished  by  the 
shorter  petioles,  blunter  leaves,  sessile  crowded  terminal  inflorescence, 
and  the  spatulate  thick  calyculate  bracteoles. 

Senecio  pachypodus  Greenman,  sp.  nov. 

Frutex  1-2  m.  altus;  ramis  ramulisque  cortice  verrucoso  tectis  gla- 
bris ad  apicem  foliaceis;  foliis  alternis  numerosis  coriaceis  lineari- 
lanceolatis  5-8  cm.  longis  2-4  mm.  latis  margine  integris  revolutisque 
basi  gradatim  angustatis  supra  glabris  subtus  dense  albo-lanatis; 
inflorescentiis  terminalibus  paucicapitatis  glabris;  capitulis  8-10  mm. 
altis  calyculatis  discoideis;  squamellis  calyculatis  lineari-attenuatis  ca. 
6  mm.  longis;  involucri  squamis  5  oblongo-lanceolatis  ca.  7  mm.  longis 
brevi-acuminatis  obtusis  penicillatisque  glabris,  basi  crassis ;  floribus  5 ; 
corollis  5-6  mm.  longis;  pappi  setis  albis;  achaeniis  columnaribus  2  mm. 
longis  cano-pubescentibus. — -  Collected  at  Camp  La  Gloria,  south  of 
Sierra  Moa,  Province  of  Oriente,  Cuba,  24-30  December,  1910,  /.  A.

graph in  hb.  Field  Museum,  cat.  no.  300835). 


326     FIELD  MUSEUM  OF  NATURAL  HISTORY — BOTANY,  VOL.  II 

A  plant  of  quite  unusual  habit  in  this  genus.  The  numerous  linear 
leaves,  tufted  at  the  ends  of  the  branches,  and  the  naked  stem  and 
lower  portion  of  the  branches,  roughened  by  the  persistent  bases  of  old 
leaves,  render  it  of  striking  appearance,  which  indeed  at  first  glance  is 
not  unlike  a  coniferous  growth. 

Senecio  rivalis  Greenman,  sp.  nov.

tisque,  basi  in  petiolam  sensim  gradatim  angustatis;  petiolis  usque  ad 
2  cm.  longis;  inflorescentiis  terminalibus  cymosis  archnoideo-tomen- 
tosis;  capitulis  discoideis  8-10  mm.  altis  calyculatis;  bracteolis  subdel- 
toideis;  squamis  involucri  8  lanceolatis  vel  oblongo-lanceolatis  8  mni.

294780,  and  hb.  N.  Y.  Bot.  Garden). 

A  well-marked  and  easily  recognized  species  on  account  of  the 
trifurcate  branching  of  stem,  the  narrowly  lanceolate  discolorous 
leaves,  and  the  close  inflorescence  of  cylindrical  glabrous  discoid  heads. 

Shafera  Greenman,  gen.  nov.  Composite,  Senecionea.

The  plant  here  described  belongs  to  the  Senecionece  and  is  related 
to  the  genus  Senecio  from  which,  however,  it  differs  in  having  the  bracts 
in  three  or  four  series  and  in  the  obtuse  style-branches.  It  seems  to  be 
related  on  the  one  hand  to  Senecio  and  on  the  other  to  Culcitium,  but 


328     FIELD  MUSEUM  or  NATURAL  HISTORY — BOTANY,  VOL.  II 

amply  distinct  from  both.  The  angulate  stem,  the  large  thick  almost 
leathery  leaves  with  a  dense  permanent  tomentum  on  the  tinder  surface, 
combined  with  the  large  heads  and  many  bracted  involucre,  give  the 
plant  a  most  striking  appearance  quite  distinct  from  anything  known 
to  the  writer.  The  genus  is  dedicated  to  the  keen  and  indefatigable  col- 
lector for  the  New  York  Botanical  Garden  Mr.  J.  A.  SHAFER.

II.— DIAGNOSES  OF  NEW  SPECIES  AND  NOTES  ON 

OTHER  SPERMATOPHYTES,  CHIEFLY  FROM 

MEXICO  AND  CENTRAL  AMERICA. 


By  J.  M.  GREENMAN. 


The  diagnoses  and  notes  following  are  the  results  of  critical  study 
in  the  determination  of  several  collections  of  plants  which  have  been 
received  from  time  to  time  during  the  last  few  years  at  the  Field  Museum 
of  Natural  History  for  identification.  Particularly  valuable  series 
have  been  received  from  Professor  CASSIANO  CONZATTI,  from  the  late 
Professor  W.  A.  KELLERMAN,  from  Mr.  CHARLES  R.  ORCUTT,  and  from 
the  late  Professor  CHARLES  R.  BARNES  and  Dr.  W.  J.  G.  LAND.  These 
collections  while  not  containing  a  large  percentage  of  new  plants  do 
include  many  which  belong  to  recently  published  and  hence  little- 
known  species;  thus  there  are  here  introduced  several  brief  notes,  relat- 
ing to  additional  localities  for  such  species,  which  it  is  hoped  may  be 
helpful  in  tracing  their  geographical  distribution. 

TRADESCANTIA  ANGUSTIFOLIA  Rob.  Proc.  Am.  Acad.  xxvii.  185  (1892). 
The  type  of  this  species  is  perfectly  matched  by  specimens  col- 
lected on  the  Cerro  de  San  Antonio  de  la  Cal,  State  of  Oaxaca, 
Mexico,  altitude  1700  m.,  18  August,  1907,  C.  Conzatti,  no.  1995 
(hb.  Field  Museum). 

Ficus  SUBROTUNDIFOLIA  Greenm.  Proc.  Am.  Acad.  xli.  237  (1905). 
Specimens  agreeing  in  all  essential  details  with  this  species  were 
collected  at  Chichen  Itza,  State  of  Yucatan,  Mexico,  28  January  and 
10  February,  1901,  E.  W.  Goldman,  no.  553  (hb.  Field  Museum).  Dr. 
Geo.  F.  Gaumer's,  no.  599,  coll.  of  1905  from  Yucatan  seems  also  to 
be  conspecific. 

PHORADENDRON   ROBINSONII   Urban,  Engl.  Bot.  Jahrb.    xxiii.  Beibl. 

Ivii.  4  (1897). 

This  species,  which  was  based  on  no.  6272  of  Mr.  C.  G.  PRINGLE'S 
Plantce  Mexicans,  has  been  collected  at  San  Nicolas,  Tehuacan,  State 
of  Puebla,  Mexico,  altitude  2000  m.,  22  June,  1908,  C.  Conzatti,  no. 
2199  (hb.  Field  Museum).  The  species  is  well  marked  and  one  of  the 
most  attractive  of  the  genus.

no.  1838  (rib.  Field  Museum)  have  been  compared  with  the  type  of  the 
above  species  and  accord  in  all  essential  details.  The  present  collec-

The  punctate  leaflets,  persistent  samara-like  calyx-lobes  and  short 
glandular  fruit  render  this  species,  although  apparently  somewhat 
rare,  an  easily  recognized  one.  It  is  well  represented  by  specimens 
secured  by  Dr.  G.  M.  Emrick  at  Tecoman,  State  of  Colima,  Mexico, 
November,  1906,  nos.  153,  154  (hb.  Field  Museum),  and  by  collections

Jose  del  Cabo,  Lower  California,  9  September,  1890.  The  species  has 
not  been  recorded  hitherto  outside  of  Lower  California.  Notwith- 
standing the  considerable  remoteness  of  Professor  CONZATTI'S  station 
from  the  peninsular  localities  for  the  species  there  can  be  no  doubt  of 
the  identity  of  the  Oaxaca  specimens  with  the  above  species.

In  general  appearance  this  species  resembles  M.  arbor eus  Cav.,  but 
it  differs  in  having  uniformly  shorter  petioles  and  fully  twice  larger 
corollas.  The  flowers  of  M.  Conzattii  suggest  those  of  M.  grandiflorus

species.  It  is  quite  possible  that  there  may  have  been  some  mixture 
of  the  seeds  grown,  as  it  is  a  well  known  fact  that  Jacquin  at  this  time 
was  growing  many  American  plants  in  Vienna,  and  it  is  not  unlikely  that 
he  may  have  confused  certain  American  importations  with  the  seeds 
which  were  supposed  to  have  come  indirectly  from  China.  At  all 
events  several  complete  specimens  at  hand  agree  in  all  essential  details 
with  the  above  species,  as  it  is  characterized  and  illustrated,  and  the 
writer  has  no  hesitation  in  referring  thereto  the  following  Mexican 
plants. —  State  of  Yucatan:  Merida,  20  August,  1865,  A.  Schott,  no.

The  species  here  proposed  resembles  /.  dimorphophylla  Greenm.  to 
which  some  of  the  collections  cited  above  have  been  referred.  I. 
oaxacana,  however,  differs  from  I.  dimorphophylla  in  having  a  distinctly 
woody  stem,  uniformly  shorter  peduncles,  persistently  pubescent  lower 
leaf-surface,  and  conspicuously  white-tomentulose  pedicels.

(24  May,  1909). 

Excellent  flowering  specimens  of  a  very  attractive  Mexican  shrub 
have  been  communicated  to  the  writer  by  Professor  C.  CONZATTI  for 
identification;  these  were  compared  recently  at  the  Gray  Herbarium 
with  the  type  of  Miss  EASTWOOD'S  Bourreria  obovata  and  prove  to  be 
identical.  Only  two  days  subsequent  to  the  date  of  publication  of 
Miss  EASTWOOD'S  paper,  Mr.  BRANDEGEE  issued  a  paper  dealing  with 
a  collection  of  plants  made  in  Mexico  by  Dr.  C.  A.  PURPUS  and  among 
other  novelties  described  Beurreria  strigosa  founded  on  Purpus'  no. 
3360.  This  material  is  almost  the  counterpart  of  the  type  of  B.  obovata, 
hence  by  the  rule  of  priority  B.  strigosa  must  give  way  to  the  earlier 
published  name.  In  addition  to  the  material  cited  in  the  above  publica- 
tion the  following  may  be  recorded:  Cuesta  de  Quiotepec,  District  of 
Cuicatlan,  Mexico,  altitude  600  m.,  21  June,  1909,  C.  Conzatti,  no.  2480

A  re-examination  of  the  specimens  on  which  this  species  was 
founded,  in  the  light  of  additional  material,  shows  the  generic  affinity 
to  be  with  Bourreria  rather  than  with  Cordia.  In  addition  to  the  speci-

vicinity  of  Merida,  20  February,  1906,  /.  M.  Greenman,  no.  360  (hb. 
Field  Museum).  The  plant  is  rather  common  at  this  station  where  it 
grows  as  a  shrub  from  i  to  2  m.  high  and  produces  corymbose-paniculate 
clusters  of  numerous  creamy  white  flowers  the  fragrance  of  which  is 
at  first  pleasing  but  soon  becomes  heavy  and  somewhat  unpleasant.

is  most  nearly  related  to  E.  viscosa  Fernald,  from  which  it  may  be  readily 
distinguished  by  the  more  oblong  leaves,  larger  flowers  and  less  glandu-

The  affinity  of  this  species  is  apparently  with  S.  carulea  Moc.  & 
Sesse  and  S.  Seleriana  Loes.  From  the  former  it  differs  in  the  low 
stature,  small  leaves,  shorter  and  reddish  to  dark  purple  flowers  and 
distinctly  racemose  inflorescence;  from  S.  Seleriana  it  differs  in  the 
color  of  the  flowers  and  in  the  exserted  stamens.

Specimens  collected  by  Mr.  C.  F.  Baker  at  Herradura,  Province 
of  Pinar  del  Rio,  Cuba,  30  September,  1904,  correspond  well  with 
the  original  specimens,  secured  by  Dr.  ED.  PALMER  in  the  vicinity 
of  Acapulco,  Mexico,  from  which  the  above  species  was  described. 
The  leaves  in  Mr.  BAKER'S  specimens  are  slightly  broader,  but 
the  habit  of  the  plant  and  detailed  characters  of  the  flower  are 
identical.

The  species  here  proposed  belongs  to  the  same  group  as  Ruellia 
Bourgaii  Hemsl.  and  R.  pulcherrima  T.  Anders.  From  the  former  it 
differs  in  the  outline,  size,  pubescence  and  texture  of  the  leaves,  smaller 
flowers,  more  lanceolate  calyx-divisions,  pubescent  ovary  and  fewer 
ovules;  from  R.  pulcherrima  it  differs  in  having  larger  leaves,  shorter 
calyx,  the  absence  of  stipitate  glands,  and  in  the  more  conspicuously 
ventricose  and  larger  corolla.

But  for  the  presence  of  a  reduced  pappus  the  plant  here  described 
might  be  referred  equally  well  to  Gymnocoronis,  and  habitally  it  re- 
sembles G.  subcordata  DC.,  but  differs  in  involucral  and  achenial  char- 
acters. In  most  cases,  however,  the  pappus  is  present  in  the  form  of 
one  to  three  papillose-clavate  much  reduced  setae,  hence  its  affinity 
seems  rather  to  be  with  Adenostemma.

Several  specimens  have  since  been  examined  and  all  possess  the  copious 
spreading  pubescence  on  stem,  leaves,  and  in  the  inflorescence,  thus 
rendering  it  easily  separated  from  G.  microcephala  Less,  with  which

A  re-examination  of  the  material  referred  to  Perymenium  grande 
Hemsl.  by  ROBINSON  and  GREENMAN  in  their  revision  of  this  genus 
shows  that  the  variety  strigillosum  may  be  clearly  differentiated  from 
Mr.  HEMSLEY'S  species  by  the  appressed  or  strigillose  pubesence  on 
stem,  branches,  inflorescence  and  petioles,  by  the  uniformly  shorter 
and  narrower  involucral  bracts,  and  by  the  thicker  leaves.  It  seems 
therefore  best  to  regard  this  plant  as  a  species  rather  than  a  variety, 
hence  it  is  here  raised  to  specific  rank  and  a  description  appended.

In  general  appearance  L.  adenotrichum  resembles  L.  glabrum  Hemsl., 
var.  hypoleucum  Greenm.,  but  differs  in  the  more  pointed  involucral 
bracts,  the  presence  of  stipitate-glandular  hairs  in  the  inflorescence,  and 
pubescent  achenes.

nos.  279188-90). 

The  writer  has  at  hand  but  a  leaf  and  a  part  of  an  inflorescence  yet 
the  plant  belongs  evidently  to  the  section  Terminates  Greenm.  and  is 
allied  to  S.  arborescens  Seem,  and  S.  copeyensis  Greenm.  From  both 
these  species,  however,  S.  Orcuttii  is  distinguished  readily  by  the  deeply 
pinnately  parted  almost  compound  leaf  and  large  heads. 

PlCRIS   ECHIOIDES   L.   Sp.   PI.    792    (1753). 

Good  specimens  of  this  species  were  collected  at  Cherubusco, 
Distrito  Federal,  Mexico,  4  October,  1910,  C.  R.  Orcutt,  no.  4283  (hb. 
Field  Museum,  cat.  no.  282479).  The  plant  is  well  established  at  this 
station,  but  the  species  seems  not  to  have  been  reported  hitherto  from 
Mexico.
